ttorney Patented st. 8, 1929 UNITE STATES PATENT ori-*ica CARL WAGLI'E,OF BALTIMORE, MARYLAND, ASSIGNOR OF ONE-HALF TO CHARLES F. W. SCHROEDER,OF BALTIMORE, MARYLAND- i ELECTRODE HOLDER FOR ELECTRIC-ARC WELDERSApplication ined June 29, 1927, serial My invention rela-tes toelectrode holders for electric arc Welders and has for its object toprovide a simple and practical device l of this character embodying abifurcated plate of spring steel adapted to firmly secure one end of.the electrode 1n adjusted angular position between the same, one of thesections of said plate having a lug formed thereon to provide a fulcrumfor the engaged end ot lo the electrode whereby to permit the same to beeasily and quickly swung into its various angular positions, the innerend of said plate being formed into a threaded shank forming aconvenient means for (onnecting an electric cable to the plate and forcarrying an insulated handle for the operator of the tool.

A further object is to provide a guard plate covering one side of theelectrode retaining plate and protecting the edges of said electrodeplate as well as the lug formed thereon from Contact with objects duringthe working of the tool whereby to prevent grounding or" the current bysaid plate.

A still further object is to provide a tool of this character of simple,strong and durable construction, eficient and reliable in performance,relatively inexpensive to manufacture, and otherwise well adapted forthe purposes for which the same is intended.

Other objects and advantages reside in the special construction,combination and arrangement of the various elements forming theinvention as more fully hereinafter dcscribed and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein:

Figure 1 is a top plan View showing the tool in operative position.

Figure 2 is a longitudinal sectional view therethrough takensubstantially along a line 22 of Figure 1, and` Figure 3 is a transversesectional view taken along a line 3 3 of Figure 1.

Referring now to the drawing wherein for 3 the purpose ot illustration lhave disclosed a practical embodiment of my invention, l provide anelectrode holder, a plate 5 formed of spring steel including a pair ofbifurcated sections open at one end and along each side and constitutingan inner section 6 and outer section 7 adapted to have one endof anelectrode 8 inserted therebetween and 'retained thereby by virtue of thereflex action'of said section. The inner .face of each of thefplatesections are provided with complementary grooves 9 and arranged atdifferent angles ,on Ethe plate and extending radially with respect lto'a .lug 10 integrallyformed at one end ofvone of said plate sections andextending transversely with respect to the edge of said plate..

The outer corner of the outer plate section 7 at. the edgethereofadjacent the lugglO is cut away as shown at 1,1 in -Fi ure l-"of thedrawing, with theI under edge osaidcutaway section bevelled as indicatedait 12, more clearly illustrated in Figures Qand.. `,Tlie lug 1,0 isspaced ,fromftheedge of the vplate section to permitthe electrode 8v tobe inserted 1therebetween and by forcingjthe electrode under thebevelled AedgelQ, using the lug 10 as a fulcrum, the electrode will thusbe forced between the platesections 6 and 7 and seated -in' one of the:grooves 9. This construction-permits thebouter end of the electrode tobe easily.' and quickly moved into any desired angle with v,respecttothe plate to adapt the tool for working'under various conditions. l Ae A metallic guard plate 13 is arranged at one side of the holder, saidguard plate beingof a substantially channel-shaped formation in crosssection as shown in Figure 3 and provided witha flange 14 along one sidethereof and a substantially arc-shaped ange 15 at its opposite sideadapted to be spaced from the adjacent edge of the holder to accommodatethe lug V10. The guard plate is arranged at that side of the holderadjacentthe inner section 6 and has interposed therebetween a pair ofinsulation plates 16 and 17, the plates 16 being arranged adjacent theguard plate and secured thereto by screws 18 which also extend slightlyinto the plate 17 arranged adjacent the inner section 6 with theinsulation plate 17 being secured at its outer edge tothe inner section6 by rivets 19 and at its inner end similar rivets which eX- tendthrough both sections of the plate.

.The inner end of the plate 5 is formed into a shank 2O having athreaded end 21,'an anrio' nular flange 22 being formed between theplate and the threaded end. The threaded end of the shank is adapted tobe inserted in one end of an internally threaded sleeve 23, the oppositeend of said sleeve having inserted therein the threaded end of a cableconnector 24 to the outer end of which the cable 25 providinga suitableelectric current is attached. A tubular handle 27 is arranged about thesleeve 23, said handle being formed ofnonconductive material and as afurther protection therefor an insulated sleei'e 2,6 is interposedbetween the lhandle and the sleeve 23. The flange 22 is of suicientdiameter to abut against one end 'of the sleeve'26, the diameter of theflange Vand said sleeve being vequal whereby to permit` the handle 27'to be insei-ted over each thereof. In this manner a safe and adequategripping surface is pro-- vided on the handle for the workman.

It is believed the4 foregoing description thoroughly discloses theconstruction and operation of the tool without further explanationthereof. I t is obvious that the invention is susceptible to variouschanges and modifications without departing from the spirit thereof orthe scope of the appended claims and I accordingly claim all such formsof the device to which I am entitled.

I claim:

1. In a tool of th'e class described, an electrode holder having meansfor selectively securing the electrode in adjusted'angular position withrespect to the holder and means formed on the holder for engaging thesecured end of the electrode whereby to constitute a pivot therefor.

2. In an electrode holder, an electrode attaching plate having meanscarried thereby for securing the electrode in adjusted angular positionand a lug formed on the plate4 and co-acting with the electrodeconstituting a fulcrum for moving the same into its var-ious angularpositions.

3. In an electrode holder, an electrode retaining plate, a lug formed atone side thereof, means carried by the plate extending radially fromsaid lug for securing the electrode in adjusted angular position, saidlug constituting a fulcrum cooperating with said electrode wherebytomove the same into engagement by said retaining means.

4. In an electrode holder, abifurcated plate having its sections formedof spring-like material and adapted to have one end of an electrodeinserted therebetween, and a lug formed at one side of said plate, meansextending radially from said lug adapted to secure the electrode inadjusted angular position with respect to the plate, said lug co-actingwith the electrode to form a fulcrum for moving the former into variousangular positions and a handle for the plate.

5. In a tool of the class described, an electrode holder comprising abifurcated springplate sections having a cut-away bevelled corneradjacent said lug, said lug and said bev- `elled edge coacting to permitthe electiLode to be readily inserted between the sections of theplate,aguard plate at one side of the bi- 'i furcated plate, insulation platesinterposed therebetween, a shank formed'on the elecgtrode plate having athreaded end for insertion in one end of an internally threaded sleeve,a cable connector threadedly carried in the' opposite end of said sleeveand an insulated handle arranged on said sleeve.

In testimony whereof I affix my signaure.

CARL WAGLIE.
